To analyse factors associated with the lack of condom use among young people at last sexual intercourse with a steady or casual partner.
A cross-sectional study involving 1170 household interviews and designed to build a representative sample of the population of young Brazilian residents aged 15-24 years (2003).
In the multivariate analysis of data, non-conditional logistic regression modelling was applied to assess the determinants of condom use at last sexual intercourse among young people with steady or casual partners.
The overall level of condom use at last sexual intercourse was high (60%), although it was significantly more common in casual sexual partnership. Cohabitation was associated with a lack of condom use in both casual and steady partner encounters. In addition, being female, having less schooling, having no work history, and per capita family income above the minimum wage were factors related to not using condoms in the group of young people who had their last sexual encounter with steady partners. Among young people with casual partners, such factors included a positive history of alcohol use, first sex at 9-16 years of age, inadequate knowledge of AIDS treatability and bereavement related to violence.
This study confirmed that the determinants of condom use among youth during last sexual intercourse vary according to whether the partner was casual or steady. Prevention campaigns should develop specific messages for each of these contexts.
分析与15 - 24岁巴西年轻居民在与固定或临时伴侣的最后一次性交中未使用避孕套相关的因素。
一项横断面研究，涉及1170户家庭访谈，旨在构建2003年15 - 24岁巴西年轻居民的代表性样本。
在数据的多变量分析中，应用非条件逻辑回归模型评估在与固定或临时伴侣的最后一次性交中使用避孕套的决定因素。
最后一次性交时避孕套的总体使用率较高（60%），尽管在临时性关系中更为常见。同居与在临时和固定伴侣关系中未使用避孕套有关。此外，在与固定伴侣有过最后一次性交的年轻人群体中，女性、受教育程度较低、无工作经历以及家庭人均收入高于最低工资是与未使用避孕套相关的因素。在有临时伴侣的年轻人中，这些因素包括有饮酒史、9 - 16岁首次性行为、对艾滋病可治疗性的认识不足以及与暴力相关的丧亲之痛。
本研究证实，年轻人在最后一次性交时使用避孕套的决定因素因伴侣是临时还是固定而有所不同。预防宣传活动应针对每种情况制定具体信息。
